BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 239,917, dated April12, 1881.

V Application filed February 19, 1881. (No model.)

To all whomitmay concern;

Be it. known thatI, HENRY O. BARKER,

a citizen of the United States, residing at Sedalia, "in the county ofPettis and State of Missouri, have invented certain new and usefulImprovements in Brick-Machines; and I do hereby declare the following tobe a full,

clear, and exact description of the invention, such aswill enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying 1 drawings, and to letters orfigures of reference forth.

Referring to the accompanying drawings, E E indicate an upright frameplanted in a suitable support or base, D, and suitably braced thereto bythe inclined braces F F. Across two of these braces is supported theshaft L of the wheel H. On one side of this wheel is a series of cogs orteeth, with which engages a pinion on the end of the shaft M, suitablyjournaled upon one side of the middle one of the braces F, and reachinginto the hopper, with means for grinding the clay therein. The-otherside of this wheel H has a guttered flange, H, with a segment removedtherefrom, as from H to H The flange is beveled at H to permit theslipping on" of the chain J connected to the center of the wheel H, andpassed around the flange and connectedto the rope J of the weight orblock 0, having the plungers c, to let the weight with its plungers falland compress the clay in the molds, thus forming into shape the clay forbricks. The rope J, connected to the weight 0, passes over a pulley, K,hung upon the frame E.

and lower ends with springs T T, the upper ones for acceleratingjtheforce of the blow of the weight with its plungers, and the lower onesfor breaking the force of the fall of the "rey ersing-bar N,whichengages with the algternating cams f f and f f? on opposite sidesof the upright frame E, so as to cause it to alternately strike theslides e 6 connected to one end of the chains N N passed around awheel,S, upon separate peripheries thereof,

to which the other ends of said chains are connected. The wheel S has ashaft, R, provided with a series of cams, 1?, adapted to operate uponthe bottoms b of the molds a, so as to raise and lower said bottoms topush out the molded clay. An arm, I, affixed to the shaft R, is jointedto a horizontal link, g, within a slot of which works one arm of alever, h, with its other arm connected, by a link, k, to thefeeder-block B d, (I being the feeder proper.

Obliquely arranged to each other, and one fastened at the front upperedge of the feeder, and the other at the lower rear edge of the feeder,are two knives, VV, to clean away any adhering particles of clay fromthe molds and the plunger-s.

An off-bearing apron can be arranged conveniently to the table A, havingthe molds to remove the molded clay therefrom as the same is pushed outthereon by the bottoms.

It will be noticed that upon the ascent of the block with the plungers,the bar N at one end will engage with the slide e, and carry it up untilthe bar is intercepted by the camf, (it-previously having been broughtunder the slide 6 by the cam f,) freeing it from said slide.Simultaneously the wheel S will be revolved, so as to cause the cams Pto elevate the bottoms b of the molds auntil the molded clayis liftedout of said molds, and so IOO upon and cause the lever is to push theblock B against, and to deliver the molded clay at one side of, themold. Duringthe further ascent of the plunger-block O the bar N will, by5 striking the cam f,be carried under the slide 0, which will elevatethe latter until the bar is intercepted and shifted by the cam f Thisaction of the slide 6 and bar N will reverse the motion of the wheel Sand its adjuncts, 10 which will have the effect to lower the.moldbottoms and move'the feeder back under the hopper and leave themolds free to receive the plungers when the block descends.

What Iclaim, and desire to secure by Letters Patent, is-

1.. In a brick-machine, the combination, with the plunger-block O andrope J J, passing over an elevated pulley, K, of the wheel H,

having the broken -away beveled flange H on one side, and a series ofcogs on the other side, and the clay-grindin g shaft M, having a pinion,substantially as and for the purpose set forth.

2. The plunger-block-operating wheel H,

having the broken-away and beveled flange on one side and a series ofcogs on the other side, in combination with the clay-grinding shaft M,having a pinion, substantially as and for the purpose set forth.

3. The combination, with the plunger-block 0 having eyes, of the rods X,having the springs T or T, substantially as and for the purpose setforth.

4. The combination of the block having the reversing-barN upright framehaving the cams 3 5 ff f f slides e e, chains or equivalents N" N wheelS, with its shaft R, provided with cams P, and mold-bottoms 22,substantially as and for the purpose set forth.

5. The combination, with the plunger block 0, having the reversing-barN, upright frame E, having the cams fff f and slides e 0, connected, bychains or equivalents N N to the wheel S, with its shaft R, providedwith cams P, movable mold-bottoms b, of the arm l, 5 link 9, slotted atone end, lever h, link 70, and feed-block B cl, substantially as and forthe purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY O. BARKER.
